Hi Era,

I encounter the following error when i use your format.
Can you give some advice ?
Seems to me that the Perl cannot accept this syntax :
open(INPUT, 'perl myscript.pl @arr_y[$num] |');

Error Msg:
Can't open @arr_y[]: No such file or directory at myscript.pl

Code:

$num = 0;

while ($num <= $#arr_y ) {
        open(FH,"< file2") or die $!;
        print "@LISTING[$num] is undercheck now.\n";
                while( <FH> ) {
                chomp;
                if($_ =~ @LISTING[$num] && $_ =~ @SLIST[$num]) {
                        $check_file = "already_appended"
                        };
                close FH;
                print "@arr_y[$num]\n";
                if($check_file ne 'already_appended') {
                        open(INPUT, 'perl myscript.pl @arr_y[$num] |');
                        open(OUTPUT, ">> file2");
                        while (<INPUT>) {       # read a line of input from myscript.pl
                                print OUTPUT;   # print it to the output handle
                        }                       
                        close INPUT;
                        close OUTPUT; 
                        print "@LISTING[$num] will be appended.\n"
                }
                else
                {
                        print "@LISTING[$num] will NOT be appended.\n";
                };
                };
        $num = $num + 1;
};
};

NAME

       Purple - Perl extension to the libpurple instant messenger library.

SYNOPSIS

	 use Purple;

ABSTRACT

	 This module provides the interface for using perl scripts as plugins
	 in libpurple.

DESCRIPTION

       This module provides the interface for using perl scripts as plugins in Purple. With this, developers can write perl scripts that can be
       loaded in Purple as plugins. The scripts can interact with IMs, chats, accounts, the buddy list, libpurple signals, and more.

       The API for the perl interface is very similar to that of the Purple C API, which can be viewed at http://developer.pidgin.im/doxygen/ or
       in the header files in the Purple source tree.

FUNCTIONS

       @accounts = Purple::accounts
	   Returns a list of all accounts, online or offline.

       @chats = Purple::chats
	   Returns a list of all chats currently open.

       @connections = Purple::connections
	   Returns a list of all active connections.

       @conversations = Purple::conversations
	   Returns a list of all conversations, both IM and chat, currently open.

       @conv_windows = Purple::conv_windows
	   Returns a list of all conversation windows currently open.

       @ims = Purple::ims
